Instructions for installation are defined in the
software documentation included with the soft­ware CD-ROM.

Software Shutdown Mode

If power is outside acceptable limits, and the
optional software is installed, the host computer
signals the UPS to shutdown. In Shutdown
Mode, the UPS disconnects power to the Battery
Backup outlets to conserve battery capacity. The
On Line and Overload indicators flash alter­nately for 20 seconds. When utility power is
restored, the UPS returns to On Line operation.

When the UPS is "Off" and there is no utility
power, it is possible to power essential equipment
connected to the Battery Backup outlets. Make
sure that only the most necessary equipment is
connected to the UPS at this time:

1. Press and hold the On/Off button until the
UPS emits a sustained tone.

2. Release the On/Off button during the sus­tained tone, to start the UPS.

3. If the Overload indicator is lit, reset the
UPS by pressing the On/Off button once to
switch it Off and again to switch it back on.

Complete what you need to do with the pow­ered equipment before the UPS battery is fully
discharged.
